Exploring the Abilities of 3D Printing and its Viability for Consumption in the Fashion Industry

Abstract With the ever-evolving state of today’s technology, designers and retailers in the apparel industry are seeking out new technological methods that have the capacity to revolutionize and individualize their brand, as well as meet consumer needs and preferences. An emerging technology is 3D printing, which utilizes computer-aided technology and a variety of filaments to construct an object. Though 3D printing technology offers the ability for rapid prototyping, a condensed supply chain, and a sustainable additive manufacturing process, there is question as to whether or not consumers are ready for 3D printed clothing to enter their wardrobes. In this creative study, the authors designed a 3D printed garment in order to test whether 3D printers could be used to make wearable clothing of similar characteristics to clothing typically made of fabric. A survey was then conducted on the University of Arkansas campus to measure consumer response to the project garment. Three primary factors were measured: prior exposure and interest in 3D printing, general fashion interest, and aesthetic appeal of the project 3D printed garment. Overall perceptions of the project garment as well as further use of 3D printing for the apparel industry were positive. The ability of this study to create a fully 3D printed garment as well as understand consumer response to 3D printed clothing provides insight into this emerging technology. The results warrant further research into its capabilities for fashion and that the fashion industry could move towards adopting this technology on a wider scale in coming years. The results indicate that a major transformation in ready-to-wear style is feasible and beneficial to the apparel industry because of 3D printing.

Exploring the Abilities of 3-D Printing and its Viability

The fashion industry encounters its most general difficulties regarding cost of samples, lead time, sustainability, and fit. An emerging technology that could solve these issues is 3-D printing, which utilizes computer-aided technology and a variety of filaments to construct an object. Though 3-D printing technology offers the ability for rapid prototyping, a condensed supply chain by way of creating samples domestically rather than internationally, and a sustainable additive manufacturing process that results in manufacturing with zero excess material, there is question as to whether consumers are ready for 3-D printed clothing to enter their wardrobes. The purpose of this study was to construct a 3-D-printed garment and measure consumer response to the application of this technology to ready-to-wear clothing. Wearability was achieved with the 3-D-printed garment, meaning it mirrors a traditional ready-to-wear garment. The survey instrument measured three factors: perception of 3-D printing, fashion interest, and opinions of the 3-D-printed project garment. Data were analyzed using a t-test for male versus female responses and descriptive statistical methods were utilized to report means and compare responses on the three factors from each age group and ethnicity. Overall the responses for all three factors were positive. The results of this research indicate that a major transformation in ready-to-wear style is feasible and beneficial to the apparel industry because of 3-D printing

A Multisite Preregistered Paradigmatic Test of the Ego-Depletion Effect

We conducted a preregistered multilaboratory project (k = 36; N = 3,531) to assess the size and robustness of ego-depletion effects using a novel replication method, termed the paradigmatic replication approach. Each laboratory implemented one of two procedures that was intended to manipulate self-control and tested performance on a subsequent measure of self-control. Confirmatory tests found a nonsignificant result (d = 0.06). Confirmatory Bayesian meta-analyses using an informed-prior hypothesis (δ = 0.30, SD = 0.15) found that the data were 4 times more likely under the null than the alternative hypothesis. Hence, preregistered analyses did not find evidence for a depletion effect. Exploratory analyses on the full sample (i.e., ignoring exclusion criteria) found a statistically significant effect (d = 0.08); Bayesian analyses showed that the data were about equally likely under the null and informed-prior hypotheses. Exploratory moderator tests suggested that the depletion effect was larger for participants who reported more fatigue but was not moderated by trait self-control, willpower beliefs, or action orientation.</p

Thunks: Evidence for Varied Harmonic Structure In an Atlantic Bottlenose Dolphin (\u3ci\u3eTursiops truncatus\u3c/i\u3e) Sound

© 2017 International Journal of Comparative Psychology. McCowan and Reiss first reported the “thunk” sound of the Atlantic bottlenose dolphin (Tursiops truncatus) during separations and discipline behavior of mother-calf dyads. This sound has been previously described as a wide-band, low frequency contact call, however the harmonic structure of this sound is more variable than previously described. Based on preliminary observations of the graded structure of thunks within our data set, we investigated the directionality of thunks with energies at higher frequencies. We recorded a bottlenose dolphin mother with her calf during the first 30-days of life, and analyzed thunk production during separation and discipline contexts. Two classifications of the thunk sound were compared to determine calf response and whether location cues were embedded in the higher harmonics of one of the thunk types. The mother oriented towards the calf significantly more during production of both thunk types during separation and discipline contexts. This sound may have potential directional information within the harmonic structure; however, we could not draw that conclusion based on our findings. Therefore, we present data here that indicates a graded structure to the harmonics of thunk sounds. McCowan and Reiss first reported the thunk sound of the Atlantic bottlenose dolphin (Tursiops truncatus) during separations and discipline behavior of mother-calf dyads. However, since this initial report, no other studies have thoroughly investigated this sound. A bottlenose dolphin mother and calf were observed during the first 30 days of life. Thunk production during separations within the mother-calf dyad and discipline behavioral events were analyzed, as thunks were predominately produced in these contexts during the original report by McCowan and Reiss. We found that variation occurs within the thunk sound, contrary to how this acoustic signal has been previously defined. We report the presence of two different types of thunks primarily present in separation events during the calf\u27s early life: the low harmonic range (LHR) and high harmonic range (HHR) thunk. LHR and HHR thunks varied in harmonic structure, but did not have significantly different peak frequencies. Furthermore, in order to determine the salience of the thunk sound to separation and discipline events, we also report on the presence of burst pulses and signature whistles when compared to thunk production. Thunks were the most produced sound during separation events, while burst pulses were more common during the mother\u27s discipline of the calf. The mother\u27s signature whistle was not as common during the course of the study, suggesting that, at least within this bottlenose dolphin mother-calf dyad, other sounds were more important for dyad communication within separation and discipline events

Alterations to the Foveal Cone Mosaic of Diabetic Patients

Purpose: We measured localized changes occurring in the foveal cone photoreceptors and related defects in the cone mosaic to alterations in the nearby retinal vasculature. Methods: The central 4° of the retina of 54 diabetic (53.7 ± 12.5 years) and 85 control (35.8 ± 15.2 years) participants were imaged with the Indiana adaptive optics scanning laser ophthalmoscope. Foveal cones and overlying retinal capillaries were imaged and infrared scanning laser ophthalmoscopy (IR SLO) images and optical coherence tomography (OCT) B-scans were obtained. Follow-up imaging sessions were performed with intervals from 4 to 50 months for 22 of the 54 diabetic participants. Results: The foveal cone mosaics of 49 of 54 diabetic participants were of sufficient quality to assess the absence or presence of small localized defects in the cone mosaic. In 13 of these 49 diabetic participants we found localized defects, visualized as sharp-edged areas of cones with diminished reflectivity. These small, localized areas ranged in size from 10 × 10 μm to 75 × 30 μm. Of these 13 participants with cone defects, 11 were imaged over periods from 4 to 50 months and the defects remained relatively stable. These dark regions were not shadows of overlying retinal vessels, but all participants with these localized defects had alterations in the juxtafoveal capillary network. Conclusions: The foveal cone mosaic can show localized areas of dark cones that persist over time, that apparently correspond to either missing or nonreflecting cones, and may be related to local retinal ischemia

Novel Oncolytic Agent GLV-1h68 Is Effective Against Malignant Pleural Mesothelioma

Malignant pleural mesothelioma (MPM) is a fatal disease with a median survival of less than 14 months. For the first time, a genetically engineered vaccinia virus is shown to produce efficient infection, replication, and oncolytic effect against MPM. GLV-1h68 is a replication-competent engineered vaccinia virus carrying transgenes encoding Renilla luciferase, green fluorescent protein (both inserted at the F14.5L locus), β-galactosidase (inserted at the J2R locus, which encodes thymidine kinase), and β-glucuronidase (at the A56R locus, which encodes hemagglutinin). This virus was tested in six human MPM cell lines (MSTO-211H, VAMT, JMN, H-2373, H-2452, and H-2052). GLV-1h68 successfully infected all cell lines. For the most sensitive line, MSTO-211H, expression of green fluorescent protein (GFP) started within 4 hr with increasing intensity over time until nearly 100% of cells expressed GFP at 24 hr. All cell lines were sensitive to killing by GLV-1h68, with the degree of sensitivity predictable by infectivity assay. Even the most resistant cell line exhibited 44 ± 3.8% cell survival by day 7 when infected at a multiplicity of infection of 1.0. Viral proliferation assays demonstrated 2-to 4-fold logarithmic replication of GLV-1h68 in the cell lines tested. In an orthotopic model, GLV-1h68 effectively prevented development of cachexia and tumor-related morbidity, reduced tumor burden, and cured MPM in both early and late treatment groups. GLV-1h68 was successfully used to treat MPM in vitro and in an orthotopic model (in vivo). These promising results warrant clinical investigation of GLV-1h68 as a novel agent in the treatment of MPM
